If you are going for stance, you are better off with spacers since you will:

-spend less on tires
-run more all season type tires
-be able to rotate your tires if you have uneven wear patterns
-not have to worry about overall diameter differences

I'm not damning the practice, it just seems like a big investment and a lot of hassle for very little return. As Azn_ignite said, 275/30 and 235/35s are the closest setup, but between the sizes you listed 265s would match better than 255s.
I'm jumping in here a little late, but everything you say here Phillip makes 100% perfect sense and is exactly why I am still struggling after months of researching and my Springtime deadline is still quickly approaching with no wheels yet to show for it:

Square: Good for all the reasons you said. I am not interested in the "stance," square looks "clean," is a no-brainer, I drive an xi, so it all makes perfect sense.


Staggered: All for looks. The #1 thing I can't get in square which I find extremely hot in staggered is the wheel - deeper lip or 'cave in the back vs. the front. I couldn't care less about stance, but the look in the wheel I find striking.

Still struggling big time with form over function on this. It's a tough one.
